Compatibility

Serious Risks

• Opening a malicious PDF from an email or website could compromise your system. Modern exploits target known unpatched flaws in Acrobat XI.
• No compatibility with modern cloud services: Acrobat XI cannot natively connect to SharePoint Online, OneDrive for Business, or Google Drive’s modern authentication (OAuth 2.0).
• Microsoft Office compatibility: As of Office 2019 and Office 365, the PDFMaker plugin included with XI may fail or crash.
